HAY-DERRICK.

SPECIFICATION forming part of Letters Patent No. 383,358, dated May 22,1388.

Application filed January 7, 1888. Serial No. 260,962. (No model.)

To aZZ whom it may concern:

Be it known that we, \VILLIAM A. HOOPER and RODNEY F. HAMBLEN, ofMaryville, in the county of Nodaway and State of Missouri, have inventeda new and useful Improvement in Hay-Derricks,of which the following is aspecification.

This invention is an improvement in hayderricks; and it consists incertain novel constructions and combinations of parts, as will behereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of the apparatus, andFig. 2 is a detail view.

, The base-frame comprises sills A A, braces B, and ring or collar 0.The sills cross each other at right angles, and are provided at theirjuncture with a step or bearing for the lower end of the mast D. Thebraces B are secured at their lower ends to the sills at the outer endsof such sills, and are secured at their upper ends to the collar 0. Thiscollar forms a bearing for the mast D,which is provided with a reenforce sleeve, E, to fit within the collar 0. The sleeve E ispreferably formed in sec tions to facilitate its application to themast, and it is also preferred to form the collar in sections forconvenience in raising the mast.

The mast is journaled, as described, in and projects above thebase-frame, and has the cross tree or beam fixed at its center to theupper end of the mast and projected equally onopposite sides of suchmast. Brace-bars extend between the outer ends of the cross beam and themast and serve to strengthen such beam in position.

In the baseframe, and usually on one of the sills thereof, we support ashort shaft, F, braced by rodf. On said shaft wejournal drum G, havingportion g and a smaller portion or hub, g, the latter being connected byrope or chain It with the mast, and the portion 5/ having the draft cordor chain H. By winding cords H h on the Windlass and the cord ii on themast in the manner shown, draft exerted on the rope H will operate toturn the mast and consequently the cross-beam, as will be understood.

A guide, H,whicl1 may be an eye or loop,as shown, is provided on thebase-frame in front of the Windlass. An outer guide-pulley, I, is

supported on the base frame at the lower outer edge thereof in aboutline with the guide H and the Windlass, and an inner guide-pulley, I, issupported on the collar 0 in line with pulley I.

Guide-pulleys J Jdepend from the opposite ends of the cross-beam. Therope H, which passes outward through guideeye H, passes through a guideon the whiflietree, thence back under the pulleys I I, and up over thepulleys J J, with its end depending and adapted to reeeive the load ofhay, to which end it may be provided with a suitable horse hay-fork orother suitable device for securing the hay. By means of the pulleys J J,I, and I we secure practically a central draft, and the mast with itscross-beam may be turned to any desired degree and may be brought intoposition for elevating the hay. \Ve provide on the whiffletree a guide,Z, for the rope.

A suitable clamp, L, (it may be a screwclamp,as shown,) may be providedfor clamping the rope at will to the whiffletree, so that slack may bepaid out between said whiflietree and the Windlass, by the amount ofwhich slack the operator may regulate the height to which the hay willbe elevated before the mast will be turned to bring the hay over therick or stack being formed.

Having. thus described our invention what we claim as new is 1. Thecombination of the base-frame hav ing an outer guide-pulley at its lowerend and an inner guide-pulley at its upper end, the

mast, the cross-beam secured centrally between 1 its ends to the saidmast and provided at its opposite ends with guide-pulleys, and the ropedisposed over said pulleys, substantially as set forth.

2. The combination of the baseframe, the mast journaled therein, thecross beam fixed thereto and having guide-pulleys for the hoisting-rope,the Windlass journaled in the baseframe, a rope connecting said Windlassand n1ast,whereby the turning of the former will 9 effect a turning ofthe latter, and the draft-rope connected with said Windlass,substantially as set forth.

3. The combination, with the base-frame, the wi ndlass, the mast havinga cross-beam,and the guide-pulleys, of the rope connecting the Windlassand the mast, the whiffietree having a guide and a clamp for therope,and the rope secured at one end to the Windlass passed through theguide ofthe whiflletree, thence disposed around the guide-pulleys, anddepending at one end from the cross-beam, substantially as set forth.

4. The improved hay-derrick consisting of the base-frame having sillscrossing each other at right angles, the diagonal braces and the collarsupported at the upper end of the said braces, the mast having thecross-beam secured to and extended equally on opposite sides thereof,the diagonal braces supporting said crossbeam, the guide-pulleys, theWindlass, the rope connecting the Windlass and mast, and the draft-rope,all substantially as and for the purposes specified.

5. The combination, in a hayderrielgof the base-frame, the mast suitablyjournaled and 20 provided with the cross-beam having guidepulleys, theWindlass supported in the basei'rame and connected with the mast, andthe rope connected with said Windlass and also disposed over the pulleysof the crossbeam, 2 substantially as set forth.
